The package exim is vulnerable to multiple issues including remote arbitrary code execution and denial of service via CVE-2017-16944 [4] and CVE-2017-16943 [5].


Since 4.90 has not been released yet and given the critical impact of CVE-2017-16943, I think it would make sense to backport the fix provided in [6].
